I derive a lot of benefit from mind-mapping in the style shown below. I usually do this in .txt files. But is there some generally accepted text file extension specifically for monospace art?

      Do you suppose there’s a way to use artist-mode with Unicode characters replacing the ASCII ones? Because looking at artist-mode, the ASCII characters are causing a bit of hesitation.

      EDIT: I do see an artist replacement table. Maybe I should paste the whole artist.el file into chat.openai and ask GPT3 whether and how I can use that to replace all four corners.
